SeaDAS 6 Benchmarks

The following benchmarks were calculated using the new seadas_benchmark.bash script. This script processes the MODIS Aqua Level-0 5 minute granule A2006167181000.L0 from Level-0 through to Level-3. (If you are a MODISL1DB user, the script will only process from Level-0 to Level-1B). If the script is run with the 'subset' option, the generated Level-1A file is stripped of its non-ocean bands before processing proceeds to Level-1B. (Boxes with two lines of times indicate processing times for a file with all MODIS bands present (top) versus times for an ocean subsetted file (bottom).

This data file and script are available from our ftp site in the seadas_benchmarks.tar.gz file. The script calculates both the CPU times (user+sys) and wall clock times (real) required for each of the following processing steps:

L0 to L1A/GEO
L1A/GEO to L1B
L1B/GEO to L2
L2 to L3 Space Binned
L3 Space Binned to L3 Time Binned
L3 Time Binned to L3 Standard Mapped Image

If you perform benchmarks, please email the results (including all machine specs) to seadas at seadas.gsfc.nasa.gov for inclusion in this table.

All times are in seconds and are indicated in [cpu time] / [wall clock time] order.
